Aluminum paint is predominantly made with aluminum flakes dispersed in an organic binder or polymer. Aluminum paints have been used as stain sealers and anti-corrosive Painttypes due largely to the platy shape of the aluminum flakes. These flakes orient themselves horizontally in the film which, after curing, appears as many overlapping plates. This reduces the penetration of potentially corrosive or extractive liquids (such as water) through the coating. The type of binder used in the coating varies, and can depend on the specific use for the product. For example, silicone-aluminum Painttypes are used for high heat applications (800-1200 degrees Fahrenheit or 427 to 649 degrees Celsius) such as boiler stacks, and alkyd-aluminum paints are used as sealers for woods and metals.
Anti-fouling paints are designed mainly for use below the water line on boats and ships to prevent marine life (barnacles, mussels, tubeworms, etc.) from attaching to the bottom, which in turn increases the drag, slows the vessel, and increases its fuel consumption. In the past, anti-foulants worked by leaching toxins that essentially poisoned marine growth to keep it from growing on the surface. This technology has fallen into disfavor because of environmental concerns – copper is still used but tributyl tin (TBT) is banned, and the trend is towards alternative biocide-free foul-release technologies, formulated to create a non-stick surface (like non-stick cookware) that minimizes the ability of fouling to adhere.
